The other booted PowerMac's using this SSD have multiple processors (G4 = and G5 examples). None of them has reported such messages so far but = those messages could be unrelated to the processor count for all I = know. This -r308247 build is "stable style" relative to performance choices = for the KERNCONF. And the KERNCONF disables/excludes PS3 and = enables/includes sc (syscons) in addition to the normal vt. I do warn that this is the environment were I experiment with the = problematical-for-powerpc clang/clang++ 3.8.0 for buildworld. Build = kernel is via gcc 4.2.1. The kernel has so-called "red zone" handling = added for signals in order to deal with the clang ABI violations (in the = stack handling). At some point when all the available llvm powerpc-target fixes are in = place I'll switch to the 3.9.0 project if I can. (Similarly for = powerpc64.) =3D=3D=3D Mark Millard markmi at dsl-only.net
